Abstract

본 발명은 다객체 오디오 신호의 부가정보 비트스트림 생성 방법 및 장치에 관한 것이다. 본 발명의 다객체 오디오 신호의 부가정보 비트스트림을 생성하는 장치는, 다객체 오디오 신호의 부호화 장치로부터 생성된 공간큐 정보를 입력받는 공간큐 정보 입력부, 다객체 오디오 신호에 대한 프리셋 정보를 입력받는 프리셋 정보 입력부, 그리고 공간큐 정보 및 프리셋 정보를 이용하여 부가정보 비트스트림을 생성하는 부가정보 비트스트림 생성부를 포함하고, 부가정보 비트스트림은 헤더 영역 및 프레임 영역을 포함하며, 프리셋 정보는 프레임 영역에 포함되는 것을 특징으로 한다. 본 발명에 의하면, 다객체 오디오 신호를 부호화할 때 생성되는 부가정보 비트스트림의 프레임 영역에 프리셋 정보를 포함시킴으로써, 다객체 오디오 신호가 재생되는 도중에도 편집자 혹은 사운드 엔지니어의 의도에 따라 설정된 음향 장면 정보를 변경시킬 수 있는 효과가 있다.
